我有以下用于裁剪图像的代码。它在Android版本4或OS Kitkat中完美运行,但它不适用于Android版本5或OS Lollipop。
我已经搜遍了整个世界,但无法找到答案...
这是我的代码:
在OS Kitkat中:此列表变量返回一个值。但是,
在OS Lollipop中:这个列表变量返回一个空的arraylist。
final ArrayList<CropOption> cropOptions = new ArrayList<CropOption>();
Intent intent = new Intent("com.android.camera.action.CROP");
intent.setType("image/*");
List<ResolveInfo> list = getPackageManager().queryIntentActivities( intent, 0 );
PackageManager test = getPackageManager();
int size = list.size();
if (size == 0) {
Toast.makeText(this, "Can not find image crop app", Toast.LENGTH_SHORT).show();
return;
} else {
intent.setData(mCapturedImageURI);
intent.putExtra("outputX", 110);
intent.putExtra("outputY", 110);
intent.putExtra("aspectX", 1);
intent.putExtra("aspectY", 1);
intent.putExtra("scale", true);
intent.putExtra("return-data", true);
if (size == 1) {
Intent i = new Intent(intent);
ResolveInfo res = list.get(0);
i.setComponent( new ComponentName(res.activityInfo.packageName, res.activityInfo.name));
startActivityForResult(i, CROP_FROM_CAMERA);
} else {
for (ResolveInfo res : list) {
final CropOption co = new CropOption();
co.title = getPackageManager().getApplicationLabel(res.activityInfo.applicationInfo);
co.icon = getPackageManager().getApplicationIcon(res.activityInfo.applicationInfo);
co.appIntent= new Intent(intent);
co.appIntent.setComponent( new ComponentName(res.activityInfo.packageName, res.activityInfo.name));
cropOptions.add(co);
}
CropOptionAdapter adapter = new CropOptionAdapter(getApplicationContext(), cropOptions);
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Choose Crop App");
builder.setAdapter( adapter, new DialogInterface.OnClickListener() {
public void onClick( DialogInterface dialog, int item ) {
startActivityForResult( cropOptions.get(item).appIntent, CROP_FROM_CAMERA);
}
});
builder.setOnCancelListener( new DialogInterface.OnCancelListener() {
@Override
public void onCancel( DialogInterface dialog ) {
if (mCapturedImageURI != null ) {
getContentResolver().delete(mCapturedImageURI, null, null );
mCapturedImageURI = null;
}
}
} );
AlertDialog alert = builder.create();
alert.show();
}
}
答案 0 :(得分:2)
我已经给了android.permission.MANAGE_DOCUMENTS权限。但面临同样的问题。经过大量搜索,我找到了解决方案。
暂时解决这个问题:
Intent mIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(mIntent, CHOOSE_IMAGE);
这会强制打开旧图库,而不是新的Kitkat文档视图。
现在,您可以通过在onActivityResult中调用以下内容来获取Uri:
Uri selectedImageURI = data.getData();
希望这有助于解决您的问题。
